Data-driven Model Reduction for Parameter-Dependent Matrix Equations via Operator Inference
Xuelian Wen, Qiuqi Li, Juan Zhang
This work develops a non-intrusive, data-driven surrogate modeling framework based on Operator Inference (OpInf) for rapidly solving parameter-dependent matrix equations in many-qu…

Convergent analysis of algebraic multigrid method with data-driven parameter learning for non-selfadjoint elliptic problems
Juan Zhang, Junyue Luo
In this paper, we apply the practical GADI-HS iteration as a smoother in algebraic multigrid (AMG) method for solving second-order non-selfadjoint elliptic problem. Additionally, w…
